1. A prosthetic heart valve device adapted for expansion and implantation into a heart chamber of a patient, the device comprising:
a collapsible and expandable stent having:
an outer section defining an interior; and
a valve support that:
extends upward into the interior; and
comprises an inflow end, an outflow end, and a cylindrical body extending between the inflow end and the outflow end, wherein a blood flow channel is defined between the inflow and outflow ends, and wherein the valve support is inverted entirely within the interior; and
a plurality of prosthetic valve leaflets disposed within the blood flow channel and configured to allow flow from the inflow end to the outflow end and prevent flow from the outflow end to the inflow end;
wherein:
the inflow end of the valve support comprises a plurality of top-most stent cells that are bent inwardly over the blood flow channel.
